T all wwn't it mm1/gj concern,.-

Be it known thatLRoBnnr WILLIARD PAIN, a citizen of the United States,residingiu the city of New York, county and State of New York, haveinvented certain new and useful Improvements in Melody-Stops forMechanically-Played Musical Instruments, of which the following is aspecification.

My invention relates to mechanical musical 1o instruments of that typewhich employs a perforated music-sheet, which sheet controls theoperation of the soundproducing devices.

More particularly my invention relates to a melody set ofsound-producing devices for such instruments, the operation of which isalso controlled by the perforated musiosheet.

I will describe a musical instrument embodying my invention land thenpoint out the novel features thereof in the claims.

In the accompanying drawings, Figure l is a vertical sectional view of amechanical musical instrument embodying my invention. Fig. 2 is an endview thereof. Fig. 3 is a detail top view. Fig. 4 is a view of a portionof a perforated music-sheet. Fig. 5 is a detail front view.

Similar letters of reference designate corresponding parts in all of thefigures.

Fig. l represents the means in a mechanical musical instrument whichlare employed to sound a note in the instrument proper and to sound anote in the additional or melody set of sound-producing devices. It willbe understood that there may be any number of the complete devices shownin Fig. l to make up a mechanical instrument of any size.

A represents a tracker-board, and a a perforated music-sheet passingthereover. The perforated music-sheet is provided with the 4o usualnote-perforations ot' a musical piece.

The perforation of the note which is to be accented or played in themelody set of soundproducing devices is cut a little in advance of theother notes in the chord. The purpose 45 of this is to cause the meanscontrolling the speaking or sounding of the note in the inelody set tobe in such position as to have the melody-note sounded at the same timeas the others in the chord. In addition to thenote- 5o perforations andthe melodyenote perfora tions a I provide marginal perforations a2,which correspond with the melody-perforations al. The'function of thesemarginal perforations is to operate a mechanism which will prevent thesound-producing devices of the melody set other than the melody-notesounding at the same time as the melody-note.

a3 represents a pipe forminga communication between a passage in thetracker-board and a passage ai, leading to a primary exhaust-chest A1.Provided over the passage of* where it enters the exhaust A1 is adiaphragm a5, which operates pallets d CLT. The pallet a6 opens apassage as to the primary exhaust A1, while the pallet a7 opens the samepassage CLS to the atmosphere. Normally the passage (LS is open to theexhaust Al.

ai represents a diaphragm for closing one end of the passage as, andthis diaphragm separates this passage from a secondary exhaust A2. Theexhaust A1 is stronger than the exhaust A2, so that the diaphragm a willnormally be in the position shown in Fig. l. lVhen, however, the exhaustA1 is cut oii from the passage a8,the diaphragm a9 will be bowed u pward.

am d represent pallets operated from the diaphragm a, The pallet amcontrols a vent of the passage (L12 to the exhaust A2, while the pallete controls the vent of the passage cl2 lo the atmosphere. The passage auis open to a pneumatic am, which through a connection o operates asound-producing device either directly or indirectly.

b represents a passage which communicates with the passage as. At oneend of the passage Z) there is a pneumatic bhwhich, as shown isnormallycollapsed. Vhen a passage as is vented to the atmosphere, apassage b is also vented to the atmosphere, and atmospheric pressurecauses the pneumatic l)l to expand. The expanding of the pneumatic b1moves a pallet b2, which opens a passage h3 to the atmosphere. At theopposite end ofthe passage lf is a diaphragm b, one side of which isexposed to an exhaust in a chamber b5. Each diaphragm b4 operatespallets b one of which, BG, controls a vent oi a chamber or passage hsto the exhaust, and the other of which, 67, controls a vent for saidchamber to the atmosphere. A pneumatic b9 is open to the chamber b3 andis normally expanded. Then the position of the pallets b 5T are changed,the pneumatic b9 is opened to the exhaust and IOS is collapsed. As itcollapses a rod bw, connected therewith, raises a pallet 511 from oif avent of a reed-cell Z212 and allows an exhaust in a chamber bis to drawair past a vibrating tongue. Any other sound-producing device may besubstituted for the vibrating tongue.

C represents a rod suitably journaled so that it may rotate on itslongitudinal axis and located adjacent the pallets Z111.

c represents a number of fingers, one for each pallet, which are looselymounted on the rod C. rlhe ends of the fingers normally rest against theedges of the pallets Z911 and in such position that a pallet may bepushed past a finger or a finger be moved onto a pallet. To hold thefingers in such position, felt c1 may be provided on the ends of thepallets or on the fingers or on both. Coacting with each finger is aspring c2, one end of which is fixed to therod C. The function of thesesprings is to have the fingers rotated with the rod when the rod isrotated.

c3 represents a lever which is rigidly connected with the rod C andthrough which the rod C is rotated.

c4 representsa link which is connected with the lever c3 and the movablemember c5 of a pneumatic c6. The pneumatic is operated from the marginalopenings in the perforated music-sheet. The same arrangement of partsshown in Fig. l, with the exception of the pneumatic b9 and the partsoperated thereby, are employed to collapse and expand the pneumatic a6.Each time a marginal opening passes over an opening on the tracker-boardthe pneumatic c6 is caused to collapse, and thus rotate the rod C, whichmoves all the fingers c over the pallets eX- cept the finger of thepallet controlling the tone being sounded. This rotation of the shaft,however, is not accomplished until the note in the melody set hasstarted to sound.

c7 represents a spring, one end of which is secured to the rod C and theother end of which rests upon a support cs. The function of this springis to insure the return of the shaft and fingerto their normal positionwhen the pneumatic cG is expanding.

The marginal openings in the music-sheet are made a little to the rearof the opening of the melody-note in each chord, but in advance of theremaining notes in the chord, and is of a length equal to nearly thelength of the melody-note.

Instead of having the fingers c act to hold .down pallets to preventsound-producing devices from speaking or sounding they may act tooperate or engage upon some other device or means, which, if held orotherwise engaged, would prevent their sound-producing devices fromspeaking or sounding. Hence wherever I have used the term pallets I meanany part or feature of a soundproducing device necessary for itssounding or speaking.

What I claim as my invention, and desire to secure by Letters Patent,is-

l. A melody set of sound-producing devices, means whereby the playing ofa soundproducing device in said set will prevent the other devices insaid set playing, and a traveling music-sheet having marginal openingsfor controlling said means.

2. In combination with a mechanicallyplayed musical instrumentcomprising soundprod ucingdevices, an additional set of soundproducingdevices forming a melody-stop, a perforated music-sheet for controllingthe sounding of the devices of the musical instrument and a device inthc melody set and having marginal openings, and means in connectionwith the melody set of devices, the operation of which means iscontrolled by the said marginal openings for preventing the sounding ofdevices in the melody set other than the melody-note.

3. In combination with a mechanicallyplayed musical instrumentcomprising soundproducing devices, an additional set of soundproducingdevices forming a melody set, a perforated music-sheet for controllingthe sounding of the devices of the musical instrument and a device inthe melody set, and said sheet also having marginal openings, and meansin connection with the melody set of devices comprising a pneumatic theoperation of which pneumatic is controlled by the said marginal openingsfor preventing the sounding of devices in the melody set other than themelody-note.

4. A melody-stop for mechanically-played musical instruments consistingof a number of sound producing devices, devices controlled by aperforated music-sheet for permitting each of said devices to speak orsound, and said music-sheet also having marginal openings and meanscomprising a rot-atable rod, fingers movable therewith which are adaptedto engage with said devices to prevent their operating, and a pneumaticfor rotating said rod the operation of which pneumatic is controlled bythe marginal openings in the music-sheet.

5. A melody-stop for mechanically-played musical instruments consistingof a number of sound producing devices, devices controlled by aperforated music-sheet for permitting each of said sound-producin gdevices to speak or sound, and said music-sheet having marginalopenings, and means comprising a rotatable rod, fingers movabletherewith which are adapted to engage with said second-mentioned devicesto prevent their operating, a pneumatic for rotating said rod theoperation of which is controlled by said marginal openings, and a springfor assistingin the rotation of said rod in one direction.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
